    I have a Standard ATX Power supply with a switch, and when I turn off my PC , I turn off the switch which kills all power to the PC. I do not do that very often but when I place my PC in sleep mode, the RGB lights go off on my mouse and keyboard. I use Corsair equipment and CUE software. But even with the software installed my lights go off and there is no logical reason for them to stay on.
    That's different from USB but on my MB, there's a BIOS setting to when lights can stay on or shut off. like for instance during sleep or machine shut down. I can also choose which USB ports would always stay on. Of course that when I switch it of at the back of PSU there's no power anywhere but that's same as unplugging it..

    Hi there

    Some PC's (Usually or invariably Laptops) have a "Charging Port" on the USB slot - maybe only 1 of several USB ports. HP ones certainly have "This feature" and probably some other makes too.

    This will still deliver a charge even when the PC is switched off -- it draws power directly from the internal PC's battery so on these "Charging Ports" you should always remove USB devices if attached to these charging ports.

    Standard (non charging) USB ports might be inactive when computer is powered off - in any case I'd always remove any external devices from a laptop after powering it off (possible exception might be a LAN cable).

    Cheers

    Yes I understand that but the OP does not have a laptop . I am not saying that some PC's don't keep RGB lights on, what I am saying that it is not logical to do so. It is a waste of electricity and will shorten the life of the RGB keyboard. In my BIOS I use S3 .

    I just checked my BIOS and there is a setting that will send power to the USB ports when the PC is turned off but it requires a hardware jumper plug to be installed on the system board. The default is to not install it.

    My ASUS motherboards have jumpers to power the USB ports either from the power supplies standby (aux) power or the normal power. When jumpered to standby the USB ports have power when I shut down the PC. They only lose power if I switch the power supply off with the switch on the power supply. Or unplug the power supply from the wall. As @NavyLCDR said this is normal. My motherboard has a power on via keyboard or mouse option. It only works if the AUX power is feed to the USB ports to power the keyboard and mouse. It looks for a key press or mouse click to turn the PC on from a cold start. This is not sleep or hibernate. Switch the jumpers the other way and they have no power when I shut down. Again, said this is normal.

    I can see this being something you might want to turn off if you have a backlight keyboard. It's not that big a deal if you don't though. I suffer from a bad back so I turned it on so I wouldn't have to lean down to turn my PC on. Bump the desk or move your mouse and your PC boots up. I got to many false starts and ended up turning it off and switching the jumpers back. I have since wired up my own switches in the top front of my case for easy access. I can reach then with a full arm extension from my computer chair.

    Yes it is normal if you have the jumpers in place. The OP gave little info on that.

    I have had this computer for a month but this only started to happen a couple of days ago.

    - I did not install/reinstall a new OS.
    - I did not update the bios.

    Yeah, apologies of sorts, I missed you very last post before I made mine.

    Did you switch which USB ports you had the keyboard and mouse plugged into? My motherboard has two jumpers, one for one group of ports and another for a second group of ports. I think one group in the dedicated ports on the motherboard, and the other jumper is for the add on ones plugged into the headers. I'd have to go read my manual again to see which jumper controls which ports.

    EDIT: As far as I know, on my motherboard, the BIOS settings don't affect whether power is sent to the ports or not. Only the jumpers do that. I can turn off my start with keyboard or mouse and the ports still get power. The PC just won't tun on with a key press, I have to press the case power button.

    Looking at this another way, would there not be a illumination timeout setting on the keyboard itself, I have no experience with wired illuminated keyboards but my Logitech Wireless illuminated keyboards fade to zero illumination a few seconds or so after the last keypress.

    If present this would likely be set using a key sequence, which could be entered accidently - especially with the finger dexterity required for some games

    It could be, I use Corsair and they use all generic MS Drivers , CUE is only used for the RGB stuff. There may be a setting somewhere on The KB. No worries Alpha
